Vulnerability Data

OPEXUS FOIAXpress Public Access Link (PAL) version v11.1.0 allows attackers to bypass account-lockout and CAPTCHA protections. Unauthenticated remote attackers can more easily brute force passwords.

CWE(s)

Related Threats

MITRE ATT&CK Enterprise Techniques

T1110 Brute Force Credential Access
Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.
T1110.001 Password Guessing Credential Access
Adversaries with no prior knowledge of legitimate credentials within the system or environment may guess passwords to attempt access to accounts.
T1110.003 Password Spraying Credential Access
Adversaries may use a single or small list of commonly used passwords against many different accounts to attempt to acquire valid account credentials.
T1110.004 Credential Stuffing Credential Access
Adversaries may use credentials obtained from breach dumps of unrelated accounts to gain access to target accounts through credential overlap.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1078 Valid Accounts Stealth
Adversaries may obtain and abuse credentials of existing accounts as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.

Mitigating Controls (NIST 800-53 r5) AI

Requires a tamper-proof, always-invoked reference monitor that cannot be bypassed by client-side logic.

Enforces all access decisions on the server according to policy rather than trusting client-supplied enforcement.

AC-7 directly enforces limits on consecutive failed logons, structurally blocking brute-force exploitation of the weakness.

Enforces information-flow rules at the server boundary instead of delegating them to the client.

Monitors and controls all external and key internal interfaces so that server-side policy cannot be off-loaded to clients.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-03 mostly match
prevents

Authentication enforcement directly includes lockout, throttling, and MFA policies that prevent brute-force attempts.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent design flaws that place server security enforcement on the client.

DE.CM-03 partial match
prevents

Behavioral monitoring of authentication activity can detect excessive failed attempts after they occur.

PR.AA-05 partial match
prevents

Proper policy-based enforcement of authorizations implies server-side controls rather than client-only checks.

PR.PS-04 partial match
prevents

Generating auth logs enables later detection or forensics but does not itself restrict attempts.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Secure architecture principles discourage client-side trust but do not directly address this weakness.

finds

Security testing can detect client-side enforcement but is not the primary mitigation.

prevents

Information access restriction is undermined when the client is trusted to enforce it.

prevents

Secure development lifecycle mandates server-side validation and prevents reliance on client enforcement.

prevents

Application security requirements explicitly call for server-side enforcement of security mechanisms.

prevents

Secure coding standards require server-side checks and reject client-only enforcement.
